These parts may besubstantially the same as in the Northrop patent. i e

Pivotally mounted on the stud or dead shaft 14 supportedby the machineframe is the builder arm 15 which carries the usual worm 16 and pickwheel 17 both of which are connected to th'e'shaft 18b -The pick wheelis given a step by step feed movement as usual through the pawl andratchet melehengages the builder cam 20 receiving rotative movement.from a going part of the machine, and the pin or roll 19 is held incontact with the cam by the usual weight 21. These parts are of usualconstruction.

Secured to the machine frame is the bracket 22 having arms 23 betweenwhich extends the pin or stud 24. The pin or stud 24serves as the axialsupport for the drums 25 and 26 which receivemovement from. the

. builder arm by the usual connection or chain 27 secured to one of thedrums.

One of the drums 26 is connected to the arm 13' by the regular traverseconnection or chain 28. the construction being such that as the builderarm is rocked by the builder 7 cam fthe ring-rail will receive traversemovement lengthwlse of the yarn carriers.

Loosely mounted upon the stud or shaft 24 is the bunch buildingsegment29 having a pin or roll 30 and a rest 31 over which passes thebunch builder chain or connection 32 the end portion 33 of which issecured to the disk 34 in one of the holes 35 provided for such purpose.The bunch building Chain 32 has its other end connected to theiarm 13 at,35. The parts so far described, with the exception ofthe plurality ofholes 35 in the disk 34 for the connection of the builder chain, may besubstantially the same as set forth in the patent to Northrophereinbefore mentioned; f v I The bracket22 carries an upper bearingsurface or portion 36 provided with a guide way .for a slotted link ormember '37 which is connected to the bunch building segment at 38. J i

.Mounted upon the bracket 32. is the seg'-' ment governor 39 having anend or finger portion 40 and the segment governor 39 passes through theslot 4l of the link 37. The segmentgovernor 39 is confined to slidingmovementon the support 36 by guides- 42 and when in itsoperativeposition or starting-to build the bunch the finger orprojection 40 of the segment governor is within the slot '41 of thelink'37 and holds the bunch building segment in operative posltionduring the building of the'bunch.

pleted with the short traverse dictated by the bunch building segmentand the connection 32 to the yarn guiding means, thebunch buildingsegment governor 39 is disengaged from the link 37, thereby entirelyfreeing the segment 29 which thereafter has'no fur: ther function duringthe completion of the yarn carrier winds.

portion of the rocking arm 43 is connected at 46 to a rod 47 one. end ofwhich is socured at 48 to a toothed rack 49 the teeth of which engagethe worm 16, the construction being such that as the pick wheel isrotated step by step during the bunch building operation, the rack 49will be moved rearivardly until when the hunch is completed the segmentgovernor 39. will be disengaged from the slot 41 of the link 37 topermit the bunch building segment 29 to move to inoperative position, asindicatedin Fig. 3, thereby jumping at oncefrom the bunch building shorttraverse to the longer service traverse.

It is desirable in some instances to bevel the end portions of thefinger 40 as at 50 and r to rcversely bevel the end wall of the slot 41as at 51 to insure the cut 'ance of the finger 4O ofthe governor intothe slot when the bunch builder is wound back to starting position.

When the winding has been completed it is usual in builder mechanisms towind back the parts into starting position and tllg present inventionprovides means for return ing the bunch building segment 29 to i;s bunchbuilding position at such time.

Tn thepresentinstance, a spring 52 has one end secured at 53 to thebunch, building segment 29 and its other e'nd secured to a fixed pointat 54 the construction being such that when the building mechanism isrun back to starting position, as usual in thisclass of .nachines, andthe rack 49 moves frontwardly, the segment 29 will be moved counterclockwise from the position indi cated in Fig. 3 to that'indicated inFig. 2,

thereby positioning the slot 41 of the link 37' for the entrance of thefinger 40 of the segment governor, so that the bunch building" elementsassume their starting position aujtomatically for building the bunch.

From the construction described it Wlll be apparent that in accordancewith the present invention the bunchon the yarn carrier is built with ashort traverse and when the bunch is'completed bysuch short traverse,the segment governor is moved todisengage' the finger 40. from th slotin" the link 41 so that the bunch building segment may at 7 once moveto'an inoperative position to permit the longer regular traverse forcompleting the windings on the carriers to start at oncewithout mergingthe traverse of the ing the latter, including a bun ch building segment,a'segment governor mounted for sliding movement independent of thesegment, and segment governor controlling means for sliding the segmentgovernor to operativeposition for traversing the yarn guiding means witha short traverse until the bunch is completed with such short traverseand then sliding the segment governor to an inoperative position tocause the I bunch building segment to become at once ineffective thatthe windings on the yarn receivers may continue with regular service,
